The story is boring in the beginning, but some-what keeps you hooked to the plot. At first it is slow. It constantly gives you side stories, but somewhere along the middle, the story takes a much more rapid pace and starts packing more action into every episode.
Like many of Tezuka Osamu's creations, it has a unique art style compared to other animes. It leans towards a Disney art style compared to your standard anime art style. The background art is fine. Nothing stands out much, which is good or else it wouldn't be called a background. The ancient statues seem very legit (and some are
based on real statues) and so are the temples.
Personally I prefer the mandarin dub version of the anime compared to the Japanese one. The OST is unique. I mean you don't here "sha-la-la" and "rune-rune-rune" in any other anime OSTs (maybe).
The main character Sharaku. Is first shown to be super childish and mentally slow. His character design really shows off his dopiness and his stupidity. His other personalty is the exact opposite of him. He is shown to be super clever and a genius. Just imagine pink next to dark purple. There, thats the contrast between the two. Other characters are not as great. They are very plain and don't really have anything unique to them.
I really enjoyed this anime. The action is pretty good it you were to compare it with the newer animes. This anime is best the way it is. The old style really goes well with the action and art in the story. If this was reanimated it would have been worse than this one.
